Showing results for "Gay Science" in Sexual & Reproductive Health

What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee.

Not Gay thrusts deep into a world where straight guy-on-guy action is not a myth but a reality: There's fraternity and military hazing rituals, where new recruits are made to grab each other's penises and stick fingers up their fellow members' anuses; online personal ads, where straight men seek other straight men to masturbate with; and, last but not least, the long and clandestine history of straight men frequenting public restrooms for sexual encounters with other men.

On January 7, 1980, in the run-up to the publication of his landmark best seller Thy Neighbor's Wife, Gay Talese received an anonymous letter from a man in Colorado. "Since learning of your long-awaited study of coast-to-coast sex in America," the letter began, "I feel I have important information that I could contribute to its contents or to contents of a future book." The man went on to tell Talese an astonishing secret: that he had bought a motel to satisfy his voyeuristic desires.
